You can use the SmartServer to integrate and manage BACnet, EnOcean, LON, LoRaWAN, and Modbus devices. The EnOcean and LoRaWAN protocols are wireless protocols where the SmartServer communicates with the edge devices using a radio frequency (RF) interface. The BACnet, LON, and Modbus protocols all support multiple communications media. All three support communication over Ethernet, and the SmartServer includes built-in support for communicating with BACnet, LON, and Modbus devices using an Ethernet interface. The BACnet and Modbus protocols also support communication using RS-485. The SmartServer IoT Pro EX model includes built-in support for communicating with Modbus RTU devices using an RS-485 interface. The LON protocol also supports communication using free topology (FT) twisted-pair cable, high-speed twisted-pair (TP-1250) cable, and power line (PL-20) communication. You can add expansion modules to the SmartServer to communicate with devices that do not use Ethernet or Modbus RTU.
